Unable to bear the thought of harming her sister, Yae fled the village on the day of the ceremony, together with her twin, Sae. During their flight, Sae slipped and fell from a mountain ledge. Yae did not see her sister's accident and ran on ahead.

When she saw she was no longer with her, Yae searched frantically for Sae, but got lost in the woods. When she returned to where her village had been, it had already vanished.

A man named Ryozo Munakata found a distressed Yae weeping at what had been the entrance gate.

Sae and Yae had given Munakata a note from Makabe that said: "You must leave this place." Munakata fled the village, but he had made a promise to Itsuki, and returned on the day of the Crimson Sacrifice Ritual.

Yae had lost her memory, and collapsed. Munkata looked after her, and in time, the two of them married.
